Solution Overview

Problem

Existing roller shutter systems are laborious to install and maintain, requiring complete removal of the movable sheet for replacing or upgrading closing elements, and they often leave open spaces that compromise security and aesthetics.

Innovation Solution

A closing element for roller shutters featuring a central portion with transversely accessible connecting portions that allow easy engagement and disengagement of connecting bars, enabling quick installation, maintenance, and adaptation of the movable sheet with modular closing elements and stiffening elements for enhanced security and customization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional closing elements with closed sockets are used, then structural integrity is maintained, but installation and maintenance become laborious requiring complete removal of the movable sheet

Engineering Contradiction:
Improveease of installationVSAvoidcomplexity of assembly process
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The closing element is segmented into a central portion and connecting portions with sockets that can be independently accessed. The socket is divided into a closed portion (for structural integrity) and an open portion (for easy access), allowing segmentation of the assembly process without compromising the whole structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The socket's open portion is extracted as a separate accessible feature from the closed socket structure. This allows the connecting bar to be inserted and removed through the open portion without requiring removal of the entire closing element or movable sheet, effectively extracting the assembly/d disassembly function from the global system level to the local component level.

Inventive Principle:
Principle #2Taking out (Extraction)

2Strength

If traditional closed sockets are used, then structural strength is maintained, but access for connecting bars becomes difficult requiring complete disassembly

Engineering Contradiction:
Improvestructural strengthVSAvoidease of connecting bar access
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The socket is designed with different qualities in different locations: the closed portion maintains structural strength and rigidity, while the open portion provides easy access for connecting bars. This local differentiation of quality allows simultaneous achievement of strength and ease of operation without compromising either property.

Inventive Principle:
Principle #3Local quality

3Reliability

If complete removal of movable sheet is required for maintenance, then structural integrity is preserved, but maintenance time and labor increase significantly

Engineering Contradiction:
Improvestructural integrityVSAvoidmaintenance time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The ability to access and remove connecting bars is extracted from the global disassembly process. The open portion of the socket allows connecting bars to be removed locally without requiring removal of the entire movable sheet, thereby extracting the maintenance operation from the time-consuming global disassembly process.

Inventive Principle:
Principle #2Taking out (Extraction)

4Ease of manufacture

If open mesh structure is used, then aesthetics and visibility are improved, but security is compromised due to open spaces

Engineering Contradiction:
Improveaesthetic qualityVSAvoidsecurity vulnerability
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The closing element is designed as a universal component that can function in multiple configurations. The central portion can be configured as either transparent (for aesthetics and visibility) or opaque/plate-like (for security), while the connecting portions with open sockets maintain the same structural function. This multi-functionality allows the same basic structure to serve both aesthetic and security requirements.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Described is a closing element (1) for roller shutters comprising a central portion (3) designed to be arranged, in use, according to a closing plane of an access opening of a room to at least partly close the access opening, and at least two connecting portions (2a, 2b) located on opposite edges (5a, 5b) of the central portion (3), each of which designed for connection of the closing element (1) with at least one other closing element (1). Each connecting portion (2a, 2b) extends about a respective axis (Xa, Xb) and defines a cavity (4) for housing a connecting bar (101). The connecting portion (2a, 2b) has an open profile so that the cavity (4) is accessible transversely to the axis (Xa, Xb).
